HORATIO G. SHIPPS, OF PHILADELPHIA, PENNSYLVANIA.

FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 331,453, dated December 1, 1885.

Application filed June 23, 1884. Serial No. 135,769. (No model.)

To all whom it may concern:

Be it known that I, Honnrro G. Snrrrs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Feed-Gutters, of which the following is a specification.

One object of my invention is to so construct a feed-cutter that there will be a uniformaction of the feed-rolls whether the amount of material passing between the same be great or small, further objects being to prevent the choking of the feed-rolls, and to insure the proper clamping of the hay or straw while it is being cut.

In the accompanying drawings, Figure l, Sheet l, is a longitudinal section of my improved feed-cutter Fig. 2, a side view of part of the same; Fig. 3, Sheet 2, an end view of the machine; Fig. 4., a transverse section on the line 1 2, Fig. l; Fig. 5, Sheet 8,a perspective View of the frame for connecting the two feed-shafts; Fig. 5i, a side view of arms forming part of said connecting-frame; Fig. 6, a plan view of part of the machine, and Fig. 7 a longitudinal section illustrating one of the features ofthe invention.

A is the main frame ofthe machine; B, the feed-table, and D D the feed-rolls, both of which are preferably iluted. The spindle a of the lower feed-roll, D, is adapted to fixed bearings in the frame A; but thespindle a of the upper roll is carried by boxes which are free to slide vertically in guides b on the frame, straps d extending from these boxes to a transverse bar, c, upon which bears a weighted lever, E, beneath the table, so that the upper roll is constantly subjected to a yielding pressure.

In order to gear together the spindles a a in such a manner that the rise and fall of the upper spindle will not throw it out of gear, I secure to the spindle c a spur-wheel, e, and to the spindle a a similar wheel, e, these spurwheels gearing, respectively, into pinions f f on short shafts g g', which are hung to the spindles a a by arms h. h', the shafts being connected together by links t', so that the pinions f f are caused to gear into each other. By this means vertical separation of the spindles a a to any necessary extent is permitted without throwing the wheels e e out of gear with y have shown two sets of arms, h h-one set inside and the other set outside of the gearing; but the outside set only may be used, if desired,

land although it is preferable to use the gearing on both sides of the machine, so as to drive both ends of the roll D', the gearing at one end of theY roll may be dispensed with in some cases.

To prevent the arms h h from dropping at the outer ends, the outside arms have segmental portions j, with interlocking teeth j', as shown in Figs. 2 and 5. As the arm h swings from the shaft a, the teeth on the upper edge of the segment of said arm would have a tendency to move outward as well as downward on the dropping of the arm, as they would follow a segmentstruck from the center of the shaft a, whereas the teeth on the segment of the upper arm, h', would have a tendency to swing inward, as they would follow a segment struck from the center of the shaft a. The teeth consequent-ly bind upon each other and prevent the outer ends of the arms from falling. In V,the present instance there are two teeth on the lower arm and three on the upper arm; but this number may be varied. In advance of the feed-rolls is a clampblock, F, which is secured to the upper end of a yoke, G, the latter being connected to a trans- Verse treadle, II, beneath the table, said treadle being acted upon by a spring, 7c, which tends to elevate it and the clamp-block.

Between the adjustable guides m on the end of the frame A is a vertically-reciprocating slide, J, which carries the inclined. cuttingknife M, and is connected by a pin, n, to an arm, N, hung by a link, p, to a stud, q, on the frame. The spindle of the lower feed-roll should be furnished with a suitable crank (see dotted lines, Fig. 2) when the machine is t0 be operated by hand, the operator in this case turning the roll with the left hand, operating the knife with the right hand, and depressing the treadle H with one foot.

In order to prevent the accidental descent of the knife before the action of the clamping- IOO block F, the treadle H, which operates the latter, is connected by a cord, s, to a springcatch, t, on the end of the frame A, this catch serving to retain the arm N in its elevated position, as shown in Fig. 7, until retracted by the depression of the treadle.

It Will be noticed on reference to Fig. 6 that the feed end of the guide-trough S is Wider than the front end, but that the sides of the latter are parallel to a point, T, in the rear of the feed-rolls, at which point the widening of the trough takes place. By this means I prevent that choking of the feed-rolls with hay or straw which is likely to occur when the said rolls are located in a tapering portion of the trough.

I claim as my inventionl. The combination of the feed-rolls D D and their spindles a a with transmittinga gearing comprising the spur-wheels e e, pinions f f', shafts g g, arms h h', and link or links i, hung to the shafts g'g, as set forth.

2. The combination of the spindles a a', shafts g g', spur-Wheels e e', and pinions j' f With the link t' and the arms h h', having interlocking teeth j', asset forth.

3. The combination of the knifeslide and its operating-arm N, the clamp-block and its treadle, and a spring-catch, t, connected to the treadle, and serving to lock the arm N when the latter is elevated, as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HORATIO G. SHIPPS.
